I want to bind listview with data from table and checkbox in each row
after that selected items using checkbox in listview should be update record in table on button click event
can someone have any idea with demo. My sample is as below

<ListView IsVisible="true" x:Name="ListView" RowHeight="50" ItemSelected="ListView_ItemSelected" CachingStrategy="RecycleElement" SeparatorColor="Transparent" BackgroundColor="Transparent">



                        <StackLayout HorizontalOptions="StartAndExpand"  VerticalOptions="Center">  
                            <Label Text="{Binding Amount}"   FontSize="11" TextColor="Black"  
                            <Label Text="{Binding Date}"   FontSize="11" TextColor="Black"  
                            <input:CheckBox  HorizontalOptions="CenterAndExpand" IsChecked="{Binding ROWCHECK , Mode=TwoWay}" Type="Check" CheckChanged="CheckBox_CheckChanged"/>  




            <Button Text="Done" TextColor="White" HeightRequest="62" WidthRequest="201" Clicked="SelectItems" VerticalOptions="EndAndExpand" HorizontalOptions="CenterAndExpand" BackgroundColor="#3DBDA0" Margin="0,0,0,62"/>  


My model class
public DateTime Date { get; set; }
public Decimal Amount { get; set; }
public String office{ get; set; }
public String user{ get; set; }
public bool ROWCHECK { get; set; }

Iteration to find value i am using is here.
IncomeCollection = new ObservableCollection<BranchViewModal>();

        for (int i = 0; i < IncomeCollection.Count; i++)  
            BranchViewModal item = IncomeCollection[i];  

            if (item.ROWCHECK)  

in this I want to select items and when click on button than record is to be updated in table as per row index
Thanks in advance

    It is necessary to add ItemSouce into ListView as the following code to bind data, please refer to ListView Data Sources.

       <ListView IsVisible="true" x:Name="ListView" ItemSource="{Binding IncomeCollection}">  

    As a matter of fact, binding bool value to an item is the same as binding other properties on Xamarin.Forms. This official ListView sample would be helpful for you: ListView.

    In addition, it is recommended to use Command instead of Event on MVVM style. Please refer to UI Interaction using Commands and Behaviors to get more details about what is MVVM and how to use Command in Xamarin.Forms.
